Sometimes, you score rounds on your phone for a friend who doesn't have a UDisc Pro account. If they end up upgrading, you probably want to link their profile to your phone so they can see all the rounds you scored for them. This also has the effect of adding those rounds to their stats.

To link a player, you just need to navigate to their profile in More > Players. Then, tap their name and select Link to Player's UDisc Pro account. You can use their username or their PDGA number if they have linked it to their account. If they aren't sure about their username, they can view it at the top of the Profile tab.
